Application of Color Sorter in Chinese Medicinal Materials Screening and Promotion of TCM Quality Standardization
2025-08-28Traditional manual screening of Chinese medicinal materials (TCM) is inefficient and error-prone, hindering quality standardization—while Color Sorter technology, especially specialized Chinese Medicinal Material Color Sorter, has become a key driver of change, complementing Optical Sorter and Color Sorting Machine applications in other sectors like Rice Color Sorter and Tea Color Sorter.
(TCM materials) like ginseng, wolfberry, and astragalus require strict screening to remove impurities (stones, broken pieces) and classify by grade—criteria critical for efficacy. The Chinese Medicinal Material Color Sorter uses high-resolution Optical Sorter modules with multi-spectral imaging to identify subtle differences: for example, distinguishing moldy wolfberries (which affect safety) from normal ones, or grading ginseng by root color and shape. Unlike generic Bean Color Sorter or Grain Color Sorter, it adjusts sorting intensity to avoid damaging fragile TCM materials, ensuring integrity.
This technology directly promotes quality standardization. Manual screening varies by operator, leading to inconsistent grades; the Color Sorting Machine applies unified parameters, ensuring each batch of TCM materials meets national standards. For instance, a TCM factory using Chinese Medicinal Material Color Sorter reduced impurity rates from 12% to 0.5%, and grade uniformity improved by 40%—meeting global TCM export requirements.
Moreover, the Color Sorter boosts efficiency, handling 3-5 tons of TCM materials daily (10x faster than manual work), enabling large-scale standardized production. Its data-tracking function also records screening results, supporting traceability—another pillar of TCM quality management.
